L110 Specification of Letters latent.

Applieation filed July A, 1814. Serial No. 252,319.

To aZZ 10720772 it may concern Be it known that l Loom Ros mvALn, a citizen of the United States, re ding at Kansas City, in the county oi Jackson and State of hfiissouri, have invented" a certain new and useful Improvement in Collapsible Boxes, of which the following is a specification.

l'viy invention relates to in'iproven'ients in collapsible boxes.

My intention is particularly adapted for use a berry or fruit box.

The object of my invention is to provide av novel collapsible box, which may be cheaply manult'actured, which is easily extended or collapsed, and which in the extended form will have great relative strength.

The novel features of my invention are hereinafter fully described and claimed.

In the accoi'npanying drawings, which illustrate the preferred embodiment of my invention, Figure 1 is a perspective view of my improved box, shown extended and partly broken away. Fig. .2- is a plan view of the box in the collapsed form. Fig. 3 is an enlarged central. or .tion of the box in its ex ended form. l; is an edge view of the box collapsed. Fig. a plan view of the strip which forms the before it is formed. Fig. 6 is a plan view of the'strip which forms the bottom before being formed. Fig. 7 is a perspect ve view of the inverted ll-shaped brace. g. 8 is a top view or" the boil, reduced, shown extended, a part of the removable bottom being broken away.

Similar characters of r ference designate similar parts in the different views.

1 designates a rectangular strip which forms the sides of the boil, and composed of sheet wood. card board or other suitable material. The strip 1 is provided with parallel transverse flexible joints 2 formed by increasing or scoring the strip at right angles to its longitudinal edges. The strip 1 is bent at the creases or joints 2 to form the shape of bor -z desired, a rectangular box being shown, and the ends are overlapped and secured together, as shown in Figs. 1 and 8. v

A second member or strip of rectangular form and having a length about the same as the width of the box is provided with a middle rectangular portion 3, which forms the bottom of the box and which is connected at opposite edges by parallel flexible joints l with two flaps and 6, the upper ends of which are folded over and respectively secured to the outer sides of opposite sides of the box, as shown in Figs. 1, 3, 4 and 8.

The bottom member or strip is provided with two parallel flexible joints 7 and 8 which extend obliquely from one longitudinal edge of the bottom member to the other longitudinal edge thereof, the angle of obliquity and the listance between the joints being dependent upon the, dimensions of the box.

The joint 7 will in all cases have one end at the upper edge and one corner of the box, Fig. 1, and will extend downwardly obliquely across the flap The disposition of both joints 7 and 8 is such that, when the member or strip 1 is collapsed fiatwise, Fig. 2, the bottom member will also be folded liatwise along the joints 7 and 8.

3V hen the be is extended as shown in Figs. 1, 3 and S, the portion 3 will be disposed horizontally, and the flaps 5: and 6 will lie against the opposite inner sides re spectively of the box. Preferably, the bottom portion 8 is disposed some little distance above the lower edge of the strip 1,

thereby leaving a space for berries or fruity Patented Jirndd, tilled.

when the boxes are piled one'on the other.

F or holding the box securely extended, it.

may have placed in it a removable bottom member 9, having substantially theinner dimensions of the box, and adapted to est upon the bottom portion 8.

if desired additional means for holding the box extended may be provided in an 1nverted U shaped brace having a transverse portion 10 adapted to be disposed just below, and against, if desired, the bottom portion 3. The'said transverse portion 10 is approximately the distance between the sides of the box to which are secured the flaps 5 and 6. ,Each arm '11 of the brace is preferably U shaped, and is adapted to embrace the adjacent side of the box, Fig. 3.

After the box has been extended, the brace isapplied thereto, opposite sides of he box being slipped into the U shaped arms, after which, the arms may be fastened to the sides by indenting them witha suitable punch or other instrument, not

shown, thereby forming indentations 12 in the arms and sides of the box, the indentations interlockin with the ones ad'acent tom member will be folded fiatwise along the. creases 7 and 8, Fig. 2. I v

I do not limlt my invention to the structure shown and described, as modifies ions,

within the scope of the appended claims, may be made without departing 'r'riimi the spirit of my invention.

Havingthus described my invention, what I ctaim and desire to secure by Let-- ters Patent, is

l. A collapsible box having a plurality of sides flexibly connected at the corners so as to collapse to flat form, and having a member located between the sides, saidsmemher having a bottom portion and two flaps respectively flexibly connected to opposite edges ot thebottom portion and extending upwardly therefrom and respectively scoured to-opposite sides ofthe box adjacent to the upper edges thereohsaid member being provided transversely across with two parallel flexible joints extending obliquely between oooosite ed 'es of said member whereby said member may collapse to fiat form when the sides are collapsed.

2. A'jcollapsible box having a plurality of sides-flexibly connected at the corners so as to collapse to fiat form, and having :1 member located between thesidcs above the lower edges thereof, said member having a bottom portion and two flaps respectively flexibly connected to opposite edgesof the bottom portion and extending upwardly therefrom and respectively secured to op- .posite sides of the box adjacent to the upper edges thereof, said member j the sides are collapsed.

7 Copies of this patent may be obtained for having two parallel flexible joints extending obliquely between opposite edges and arranged to permit the member to collapse to fiat form when 8. A collapsible box having a plurality of sides flexibly connected at the corners so as to collapse to flat form, and having a member located between the sides, said member having a bottom" portion and two flaps re-v spectively connected to opposite edges of said portion and extending upwardly therefrom and respectively secured to opposite sides of the box adjacent to the upper edges Vtangular strips disposed at right angles to When ad five cents each, Washington; D.

tween opposite sides of the box for holding said sides and member from collapsing.

4. A collapsible box comprising two rec.-

each other, one strip having its ends secured toeach other and provided with transverse flexible joints located at the corners of the box, so as to permit of the collapse tofiat term of the strip, the other strip having its opposite ends respectively secured to the opposing. strip adjacent to the upper edge thereof and at opposite'sides of the box and provided with two parallel transverse flexible joints disposed at equal distances from the upper edge of the box. 1

5. A collapsible box'comprising a rectangularstrip having its ends secured to each other and provided with transverse flexible. joints at the corners of the box, the strip forming the sides of the box, and a second strip forming the bottom of the box and disposed at right angles to the first strip and having its ends secured to the other strip adjacent to the upper edge thereof and at opposite sides respectively of the box, the second strip having two transverse iiexible'joints disposed at equal distances from the upper edge oi the box and above thejlower edge thereof.
